Mr & Mrs H, Thurning Nr Oundle, Northamptonshire

As first time self builders embarking on a new build and barn conversion “forever home” property, that would require our life savings (and then some), from the outset we were well aware that we would be dependent on various professionals to correctly advise us.

Since the digging of the first test holes, through to ridge beam specification and install plus the design of a steel frame that Gustave Eiffel would be proud of, Andy exudes a confidence in his abilities that is extremely comforting.

He has performed well above the normal remit: Liaising with the steel frame builders and guiding our architects during the design and build as well as advising us on site, for which we are very grateful.

We would not hesitate to recommend Andy / SEA Structural Engineers.
